This double storey glass extension in central London utilises the best in architectural glass technology to achieve a minimal, all glass façade.

Kensington Gate is a listed building in a conservation area and sensitivity was required when extending. In order to create a glass extension with as little disruption to the existing building as possible our minimal windows sliding glass doors were used to both floors.


On the ground floor, the minimal windows open at the centre leaving a flush threshold across the sliding base track.

To the upper floor, as the minimal windows open, a frameless glass balustrade protects the fall whilst not changing the appearance of the door opening. The result is an identical set of sliding doors to the upper floor bedroom terrace.

A structural glass roof with steel supporting sections returns over the minimal windows enclosing the upper storey space and ensuring high levels of thermal insulation.

Back painted glass covers the building structure between both floors for a sleek, all glass façade to the glass extension.
